Little eye read button not crossing out.

[Koshin89]

The little eye next to the chapter is not crossing out after reading a chapter, noticed it when I went into the updates section to start reading chapters for the updated manga I had selected. After returning to the update section after reading the new chapters the little eye was not crossed out and crossing it out manually was not working either, If I read a new chapter and came back to the update section what I selected as I read the eye uncrossed itself.

I logged out and back in and that fixed it for me

sometimes it can take longer to apply, especially when the site is under high load (can take minutes/hours then).
and make sure an extension like Privacy Badger is not blocking it.
